Do you expect to trigger more than 127 tracks/pages in a setup?
The concept of my proposal comes from: Ok I want to trigger this page so I assign it to this note. And then I assign this track to the next note.
Very different from: Ok, to trigger this particular page I have to *reads the manual* play a g#5 on midichannel 14 at velocity 78.
I am not trying to be able to trigger everything there is to trigger at anytime. I just want something that is musical and intuitive.
